AEIS英语语法难题：关系代词作主语时的省略（一）

　　中国人没有英语母语环境，语法是帮助其最快学会使用这门语言的唯一方法，同时语法学习不仅是为AEIS考试，而是正确运用语言的方法，刚接触语言，语感形成很重要，使用语法来辅助语感的实现尤为重要。今天小编就主要分析AEIS语法重点：关系代词。

　　关系代词在定语从句中作宾语时常被省略,而作主语时一般是不能省略的。但在某些特殊情况下,尤其是口语中,作主语的关系代词有时可以省略。

　　在主句以that, it, there, here 开头的复合句中。

　　例如:

　　That' s a thing ( that) might happen to any man.这种事情谁都难免。

　　There was a man ( who) asked for you, sir .先生,刚才有人找您。

　　Here is an instruction book ( that ) will tell you how to operatethemachine.这儿有一本说明书,它会告诉你怎样操作这台机器的。

　　在以疑问代词who, what 开头的复合疑问句中。

　　例如:

　　Who was the man ( that) called on you a moment ago?刚才来拜访你的那人是谁?

　　What is the staff about the door ( which ) swings both ways?在门上摇来晃去的是什么东西?

　　What was it (that) set me to watch the other so?是什么使我这样观察另一种事物?

　　在以there be引出的定语从句中。

　　例如:

　　1 love him, and he loves me, and that s all(that) there is toit.我爱他,他也爱我,就是这么一回事。

　　We would have left town with the dog first, along any road( that) there was to go.我们本可以一开始就带着狗离开城镇,沿着任何一条可行的路走的。

　　You may be interested in some ceremonials ( that ) there werein religions. 你也许对过去的某些宗教礼仪感兴趣。

　　当主句谓语动词为have时。

　　例如:

　　We have only one article ( that ) should be written today. 我们今天只有一篇文章要写。

　　We have two-week' s allowance ( which) should be here.只允许我们在这里呆两周的时间。

　　在作主语的关系代词that后紧跟了ever ,其前的先行词被形容词最高级或first, only, last 等词修饰时。

　　例如:

　　He is the bravest man (that ) ever breathed.他是那位空前的勇士。

　　She was the first woman ( that ) ever climbed Mt. JolmoLungma.她是登上珠穆朗玛峰的第一位女性。

　　在被动语态中,动词be亦可省去。

　　例如:

　　This is the only moonstone (that was) ever found.这是发现过的唯一的月长石。

　　It was the strangest sight (that was) ever seen.这奇观是罕见的。

　　当定语从句中作主语的关系代词后有插入语I think, I know, he said, he believes,he hopes等时。

　　例如:

　　He asked for something (that) I knew couldn’t be provided.他所要求的东西，我知道是无法提供的。

　　He stopped his son fromdoing things (that) he thought werewrong.他不让他的儿子干他认为是错误的事情。

　　He sold the books to thepeasants (which) he said tell themhow to breed new varieties of wheat.他把那些他说是讲解如何培植小麦新品种的书卖给了农民。

　　如果先行词为两个或两个以上并列的定语从句所修饰,而且代词相同，则只需保留第一个作主语的关系代词,其后的可省去。

　　例如:

　　Just consider that we use hardly one hundred thousandth of theheat that there is in coal and (that ) could be extracted from it!请想一想,储藏在煤里并可以被提取的热量,我们所利用的还不到十万分之一。

　　Then there are very many words which appear to be ordinaryeveryday words but ( which ) are being used in specialized technicalsenses. 于是就有很多单词看来好像是普通的日常用词,但在使用中却带有专业技术上的含义。

　　有时我们也可以见到第一个关系代词省略的例子,但其后的关系代词一般要保留。

　　例如:

　　Apart from repeating sentences (that) begin in the same wayor that follow similar structural patterns, you can repeat keywords or phrases at various places within the paragraph. 除了重复以同样方法开头或者有相同的句型结构的句子外,你还可以在本段里各处重复关键词或短语。
